Allagash Wilderness Waterway planning

Allagash Wilderness Waterway wildlife & seasons

What lives here and what each season brings, so you time the trip for the experience you want.

Wildlife

One of the densest moose populations in the East, plus black bears, bald eagles and native brook trout in the cold tributaries.

Season	Window	Conditions
Spring	May – mid-June	High water moves you along, but black flies and mosquitoes peak through mid-June.
Summer	Late June – August	Stable water and warm days — the peak season on the waterway.
Autumn	September	Cool, bug-free and colorful, but water runs low by late September.
Winter	October – April	The corridor belongs to snowmobiles and ice anglers; extreme cold.

Filter or treat all natural water sources. Potable water is occasionally available at ranger stations such as Churchill Dam — don't count on it.
